Title: Pigment compositions
Inventor: TWITCHETT HARRY JAMES
IPC: C08K5/00
Filed: 1957-10-30
Abstract: A stable dispersion of a coloured or fluorescent pigment and a synthetic polyamide is made by milling together in the presence of water a coloured or fluorescent pigment and a synthetic polyamide in the form of fine particles.  The water may contain alcohol, acetone, urea or inorganic salts and dispersing agents, e.g. disodium methylene-bis-(naphthalene-2-sulphonate), during the milling.  The pigments used, of which many are specified, may be organic or inorganic.  The products may be used for coating paper, card or textiles or for colouring granules, chips or flakes of polymeric materials prior to moulding or extrusion, e.g. they may be added to polyesters or polyamides prior to spinning.  In the examples, fine particles of polyhexamethylene adipamide or polycaproamide are milled with copper phthalocyanine, copper octaphenyl phthalocyanine, carbon black, cadmium sulphide, a mixture of cadmium sulphide, titanium dioxide and carbon black, cobalt hexadecahydrophthalocyanine, nickel hexahydrophthalocyanine, copper tetratolyl mercaptophthalocyanine, the 1:2-chromium complex of 2-carboxy-benzene-azo-11-(o-tolyl) -31-methyl-51-pyrazolone, perylene3:4:9:10 - tetracarboxydi - (31:511 - dimethyl phenyl imide), aniline black, chlorinated copper phthalocyanine, copper tetraphenyl phthalocyanine, 3:31-azopyrene, ultramarine, cadmium sulpho-selenide, iron oxide, chromium oxide, the bis-iminazole from perylene-3:4:9:10-tetracarboxylic acid and o-phenylene diamine, the nickel complex of 4-bromo-1:2-bis-(21-hydroxy - 11 - naphthylidene) - phenylene diamine, 1:4:12:12 - tetrachlorophthalo perinone, 2:8 - di - (211,611 - dimethyl phenyl) - anthra - 11:91 (N): 101 (N): 5 - dipyridazone, 2:5 - dichlorobenzeneazo - 21 - naphthol - 31 - carboxyaniline, 2-nitro-4-methoxybenzeneazo-21 - acetoacetaniside, cobalt phthalocyanine, the iron complex of 1-nitroso-2-naphthol, bis quinacridone, perylene - 3:4:9:10 - tetracarboxy - di - (41 - methoxydiphenylimide), 4:41 - diethoxythioindigo, 1:5 - dibenzoylaminoanthraquinone, 1:5 - di - (p - methoxybenzoylamino) - 4:81 - dihydroxyanthraquinone, 4:8 - dibromo anthranthone, benzeneazo-b -naphthol, and 5-hydroxy-1:4-di-p-toluidino anthraquinone, the resultant compositions being mixed with polyhexamethylene adipamide or polycaproamide chips, melted and spun into yarns, or moulded, or mixed with casein and used for coating card or paper.

[Classes 75 (ii) and 75 (iv)] A refractor plate for use in lighting apparatus for preventing the emission of light in unwanted directions is of generally uniform thickness and has a plane first surface 23, Fig. 5, and a light transmitting second surface formed with symmetrical prismatic elements having plane sides 36, 36<1>, or with contiguous conical prismatic elements (not shown), the angle P which the sides 36, 361, or the sides of the conical elements, make with the plane 23 being substantially equal to 2/y (90 degrees - C), where C is the critical angle of the medium of which the refractor is made and y is an odd integer greater than one. The plate shown is of glass having a refractive index of 1.5 and a critical angle of 42 degrees, and the angle P, given by the above formula when y=3, is 32 degrees. No rays are transmitted at angles to the vertical higher than that of the ray 28 which is 47 degrees to the vertical. Fig. 12 shows a refractor 90 for use with a rectilinear light source mounted along the aisle of a railway coach and provided on its upper surface with longitudinally extending prisms 92 which spread light away from the vertical and light depressing prisms 93 which lower the light to produce two generally divergent light beams directed towards the seats. Transverse prisms 98 constructed in accordance with the invention are provided on the lower surface of the refractor extending 30 degrees approximately each side of the vertical central plane through the light source, so that the rays at high angles to the vertical are not emitted through the longitudinal central portion of the refractor.

Title: An improved broadband antenna
Inventor: WONG SAM HEM
IPC: H01Q21/00
Filed: 1968-07-19
Abstract: 1,220,395. Aerials. NORTH AMERICAN ROCKWELL CORP. 19 July, 1968 [5 Sept., 1967], No. 34680/68. Heading H4A. A symmetrical aerial assembly comprises a plurality of slotted travelling wave line sources, each source having two halves which are disposed at an angle other than 180 degrees to each other about a central feed point. The assembly has a first plane of symmetry which is parallel to the line sources and a second plane of symmetry which is perpendicular to the first. The line source halves in each quadrant defined by the said planes are coupled by a common feed to a different port of a microwave hybrid device from the line source halves on the opposite side of the first plane. In a first embodiment, a broadband aerial assembly comprises a stack of six mutually parallel centre-fed linear slotted arrays 10, Fig. 4, each having two mutually angled portions 10a, 10b diverging from a feed point at which is a power splitter, for example, a metallic centrepost (18), Fig. 5 (not shown). Metal pieces 13 of channel or angle cross-section secure the arrays together, and provide means of attachment to electro-mechanical scanning apparatus. A waveguide feed is taken rearwardly from the centre of each array and an upper set 14a of three feeds in parallel is connected to one input port of a hybrid junction 15, whilst a lower set 14b of three feeds in parallel is connected to the other input port thereof. The difference port of the hybrid junction 15 gives an output adapted for single plane (elevation) monopulse operation. The angling of the arrays about their centres prevents changes of beam direction in azimuth with frequency variation, since the beams from the two halves of an array tend to swing in opposite directions. In a second embodiment, Figs. 6 and 9, four sets of arrays A, B, C, D are symmetrically arranged about two mutually perpendicular planes, adjacent ends of the sets beingfed from the four ports of a dual plane hybrid bridge 16. In this way difference outputs for both elevation and azimuthal monopulse operation are made available. The lower sets of arrays may be angularly squinted relatively to the upper sets of arrays, in addition to the angular squinting in azimuth between the left-side and right-side arrays, as shown in Fig. 9. Amplitude tapering of the aperture field distribution may be effected by predetermined variation of the slot dimensions across the arrays. It is stated that electronic beam scanning means may be incorporated in the array feeds, to supplement the mechanical scanning.

During pay-out of the cable A, as when snatching loads from the ground by aircraft in flight, the drum B is rotated over the thread C in a direction causing the piston D to move into the cylinder C so that fluid is forced through a pipe leading to a fluid spring or hydraulic reservoir. A variable orifice metering tube P is mounted in the cylinder C and projects through an orifice H in the piston to restrict the rate of movement. After the snatching operation the pressure in the cylinder C forces the piston D outwards causing the drum to take-up the cable A. An hydraulic ram T operates as an end stop to limit the take-up of cable A and is used to pay out the required length of cable prior to a snatching operation.
